[Class 83 (iv)] A riveting-machine that is self-adjusting for rivets of various lengths has the motion transmitted through a linkage that moves as a whole until the set encounters the end of the rivet, the linkage then coming into action to give an increased mechanical advantage during upsetting the head. The abutment 3 is connected at 4 to a slotted frame 2 slid into the main frame 1 and secured by a cross-pin 39 and by the fulcrum pin 37 of the lever 40. A piston-rod 7, 14 carries pistons 6, 12 in tandem and has a gudgeon pin 46 engaging a slot in a link 35 pivoted at 36 to the lever 40 and having a cam surface 52 engaging a roller 32 on the riveting- plunger 29. The roller is maintained in contact with the cam by a spring 33. Fluid pressure admitted behind the piston 6 for the power stroke passes also by ports 16, 15 behind the piston 12 which is double acting, both pistons being operative in the power stroke and the piston 12 alone acting in the return stroke. The control valve is as described in Specification 562,411. On the power stroke springs 49 rock the lever 40 and cause the linkage to move as a whole until resistance is encountered. During this part of the stroke, a spring 55 moves a wedge 44, slidable on a rod 53 and supported by the frame, to back up a heel 42 on an arm 41 integral with the lever 40. On meeting resistance, the wedge prevents retrograde movement of the lever 40 and the link 35 turns on the pin 36 causing the cam 52 to advance the plunger 29 and close the rivet. During the return stroke, a projection 62 on the piston-rod engages a projection 63 on the wedge to return it to its initial position and permit the resetting of the remaining parts of the linkage.
